Installing and using jnettop

jnettop – a utility for viewing traffic statistics in real time, sorted by hosts / ports.

The installation command in Ubuntu/Debian:

sudo apt-get install jnettop

The installation command in CentOS:

sudo yum install jnettop

An example of a simple start:

sudo jnettop

An example of a start with a network interface:

sudo jnettop -i eth0

I’ll describe the possible startup options:
-h (help)
-v (view version)
-c (disable content filtering)
-d (write debugging information to a file)
-f (reading the configuration from the file, if not specified, then the file is searched for ~/.jnettop)
-i (to capture packets from the specified interface)
–local-aggr [none|host|port|host+port] (set local aggregation to the specified value)
–remote-aggr [none|host|port|host+port] (set remote aggregation to the specified value)
-n (do not resolving IP to DNS names)
-p (inclusion of promiscuous mode to receive all packets that come to the network interface)
-s (selects one of the rules defined in the .jnettop configuration file (by its name))
-x (allows you to specify a custom filter rule. this allows you to use the syntax of the tcpdump style. do not forget to include the filter in quotation marks when starting from the shell)
